“Forgot the Engineer outfit that this was all in reference to.”
The German officer was Lt Colonel Joachim Peiper of the Waffen SS.
The Engineers were the 291st Engineer Combat Battalion. They blew up every bridge Peiper needed to cross the Meuse River.

What O.V. said. I knew the story about Peiper, and that’s what I used to look it up, then I didn’t use the details, because it wasn’t them alone, and Peiper was pretty profane, and I’m just a timid SOB. ;^)
